Decimal.LessThanOrEqual(Decimal, Decimal) Decimal.LessThanOrEqual(Decimal, Decimal) Decimal.LessThanOrEqual(Decimal, Decimal) Decimal.LessThanOrEqual(Decimal, Decimal) Operator

定義

傳回值,指出所指定的 Decimal 是否小於或等於另一個指定的 DecimalReturns a value indicating whether a specified Decimal is less than or equal to another specified Decimal.

public:
 static bool operator <=(System::Decimal d1, System::Decimal d2);
public static bool operator <= (decimal d1, decimal d2);
static member ( <= ) : decimal * decimal -> bool
Public Shared Operator <= (d1 As Decimal, d2 As Decimal) As Boolean

參數

d1
Decimal Decimal Decimal Decimal

要比較的第一個值。The first value to compare.

d2
Decimal Decimal Decimal Decimal

要比較的第二個值。The second value to compare.

傳回

如果 d1 小於或等於 d2,則為 true;否則為 falsetrue if d1 is less than or equal to d2; otherwise, false.

備註

方法會針對Decimal值定義小於或等於運算子的運算。 LessThanOrEqualThe LessThanOrEqual method defines the operation of the less than or equal operator for Decimal values. 它會啟用如下所示的程式碼:It enables code such as the following:

using System;

public class Example
{
   public static void Main()
   {
      Decimal number1 = 16354.0699m;
      Decimal number2 = 16354.0695m;
      Console.WriteLine("{0} <= {1}: {2}", number1, 
                        number2, number1 <= number2);

      number1 = Decimal.Round(number1, 2);
      number2 = Decimal.Round(number2, 2);
      Console.WriteLine("{0} <= {1}: {2}", number1, 
                        number2, number1 <= number2);
   }
}
// The example displays the following output:
//       16354.0699 <= 16354.0695: False
//       16354.07 <= 16354.07: True
Module Example
   Public Sub Main()
      Dim number1 As Decimal = 16354.0699d
      Dim number2 As Decimal = 16354.0695d
      Console.WriteLine("{0} <= {1}: {2}", number1, 
                        number2, number1 <= number2)

      number1 = Decimal.Round(number1, 2)
      number2 = Decimal.Round(number2, 2)
      Console.WriteLine("{0} <= {1}: {2}", number1, 
                        number2, number1 <= number2)
   End Sub
End Module
' The example displays the following output:
'       16354.0699 <= 16354.0695: False
'       16354.07 <= 16354.07: True

不支援自訂運算子的語言可以改為Compare呼叫方法。Languages that do not support custom operators can call the Compare method instead. 它們也可以直接呼叫LessThanOrEqual方法,如下列範例所示。They may also be able to call the LessThanOrEqual method directly, as the following example shows.

Module Example
   Public Sub Main()
      Dim number1 As Decimal = 16354.0699d
      Dim number2 As Decimal = 16354.0695d
      Console.WriteLine("{0} <= {1}: {2}", number1, number2, 
                        Decimal.op_LessThanOrEqual(number1, number2))

      number1 = Decimal.Round(number1, 2)
      number2 = Decimal.Round(number2, 2)
      Console.WriteLine("{0} <= {1}: {2}", number1, number2, 
                        Decimal.op_LessThanOrEqual(number1, number2))
   End Sub
End Module
' The example displays the following output:
'       16354.0699 >= 16354.0695: False
'       16354.07 >= 16354.07: True

這個運算子的對等方法是Decimal.Compare(Decimal, Decimal)The equivalent method for this operator is Decimal.Compare(Decimal, Decimal)
